Cyrus IMAP Server: Special Characters¶
This document is supposed to be a repository of "special characters" used in Cyrus naming of users, folders, directory paths, etc.
Current Uses¶
- (LMTP) Separation of postuser and target mailbox for delivery 
- (LMTP) Separation of username and submailbox for delivery 
- (IMAP) Flag at end of login name that indicates that LIST should return LSUB results (when imapmagicplus is set) 
- (POP3) POP a subfolder directly (e.g. rjs3+foo POPs user.rjs3.foo) 
- [mailbox names] Hierarchy separators 
- [mailbox names] In unixhierarchysep, ^ is the part of the internal name that represents a '.' 
- [usernames] These are realm separators for the purposes of authentication 
Future Uses¶
- IMAP LIST filters (e.g. rjs3+foo will only list folders that match foo*) 
- possibly other interpretations here: - rjs3+foo will do an effective chroot(foo.) - rjs3+foo will only list folders in user.rjs3.foo*
